Incredible facts

Many people have such talents as singing, dancing, but there are also those who have almost superhuman abilities.

Some of them acquired their abilities suddenly, after experiencing trauma or accident. For others, their gift brings many difficulties in life. And there are those who are practically genetically predisposed to their supernatural qualities.

Here are the stories of several people with amazing abilities.

After brain injury, a small percentage of people may develop unusual abilities. They are called savants... Typically, savants have amazing mathematical abilities, or, for example, can draw an entire city in striking detail.

However, by the end of the year, he discovered amazing calendar abilities, for example, naming all Mondays in 1980. In addition, he remembered all the details of each day, as is the case with hyperthymesia - exceptional autobiographical memory.

While many people may envy such abilities, savants acquire such abilities due to the fact that their the brain takes everything literally and sees details that we don't pay attention to. This is why many of them find it difficult to pass exams at a school where broader questions are asked.

Vietnamese peasant Thai ngoc(Thai Ngoc) suffered a fever in 1973 after which he developed severe case of insomnia... At first he thought that this one would pass in another week, and did not attach any importance to this.

According to scholars, Tibetans inherited this gene from the Denisovans - an extinct species of people... Denisovans lived in the area where Tibetans now live, and their remains contain the same EPAS1 gene.

4. Elizabeth Sulcer - synesthesia

Dean started running in high school, and while his classmates did 15 laps, he could run 105 laps until he was asked to stop. He once ran 50 marathons in 50 days.

7. Tibetan monks

In South Asia, especially in Tibet, monks claim that they can regulate your body temperature using an ancient form of meditation called tummo. According to Buddhism, apart from the life we live, there is a kind of friend of reality. By practicing tummo, monks can go to that other world.

They generate a lot of heat during practice. Scientists who studied Tibetan monks were surprised to find that the temperature of their toes and hands increased by 8 degrees Celsius.

Tummo- is not the only form of meditation practice by Tibetan monks. They are also able to meditate slow down metabolism which controls the rate at which the body breaks down calories.

People with a low metabolic rate gain weight faster because their bodies do not break down calories as quickly. By meditating, monks can lower their metabolic rate by 64 percent which allows them to conserve energy. For comparison, in ordinary people, metabolism is reduced by 15 percent during sleep.

8. Chris Robinson - fortune-telling dreams

Scotsman Chris Robinson woke up one day with a very realistic dream, in which he saw planes colliding in the air. Since then, he began to see the future in his dreams.

Robinson wrote down the place he saw in his dream and put it in an envelope. When the researchers arrived at the desired location, they opened the envelope and found that it matched.

In another experiment, he was asked to guess the item in the box, and out of 12 times he guessed it 2 times.

9. Eskil Ronningsbakken - extreme balancing

Eskil Ronningsbakken(Eskil Ronningsbakken) is one of the most amazing extreme sports that learned the art of balancing from the age of five... At 18, Ronningsbakken entered the circus, where he worked for 11 years.

Now that he is in his 30s, he risks his life driving cycling upside down zipline over a canyon, cycling backwards on one of the most winding roads in Norway, or performing a handstand on a bar hanging from a balloon.
